Web Platform Features in Windows Consumer Preview

  • [アーティクル]

Internet Explorer 10 in the Windows Consumer Preview introduces a number of new or updated Web platform features when compared to the IE10 in the Windows Developer Preview released September 13, 2011. Some of these shipped in the fourth IE10 platform preview released November 29, 2011, and have been blogged about since; some are new in the Consumer Preview.

New or Updated Web Platform Features

The following Web platform capabilities in the Consumer Preview were not in the Developer Preview:

  • Cross-Origin Resource Sharing (CORS) for XMLHttpRequest (spec / post / dev guide)
  • CSS -ms-user-select property (post / dev guide)
  • CSS3 font-feature-settings property to access advanced OpenType® features (spec / post / dev guide)
  • Document setting to enable floating point values in CSS-OM (post / dev guide)
  • HTML5 BlobBuilder API and new APIs to save or open files (spec / post / dev guide)
  • HTML5 track element for HTML5 video captions (spec / post / dev guide)
  • Interoperable HTML5 Quirks mode (post / dev guide)
  • JavaScript Typed Arrays (post)
  • Meta tag to alert user that site requires ActiveX add-ons available only in desktop IE10 (post)
  • Removal of legacy graphics features from IE10 standards mode (post)
  • Changes to support latest HTML5 WebSocket API (spec)
  • Web Worker thread pooling

Across the board, we’ve improved performance and addressed feedback on the platform features that were available in the Windows Developer Preview but not IE9:

More to Come: User Interface Improvements

Metro style Internet Explorer in the Windows Consumer Preview contains many user interface changes and additions compared to the Windows Developer Preview. You can get a taste for these in what Gizmodo wrote about Internet Explorer 10. We will be blogging about these new features in the coming days both here and on Building Windows 8.

    Thank you for this list of features that Windows 7 users cannot test.

    Can we see the Internet Explorer 10 Consumer Preview as a beta-version of IE10?

    @Yannick: If I understand your question correctly, yes, you can consider IE10 in the Windows 8 Consumer Preview to be what used to be called the first Beta release.

    Which free, open & non-DRM-encumbered audio format(s) does IE10 support for CSS-OM media query list listeners? Which free, open & non-DRM-encumbered video format(s) does IE10 support for CSS-OM media query list listeners?

    @Jackson: You misunderstand what a CSS media query list is. It's not about HTML5 media elements; it's about CSS media queries. See the linked spec.

    a couple issues so far in desktop ie:

  1. when refreshing a captcha dialog , keep getting a popup dialog to stay on the page or leave the page. doesn't happen in ie9.
  2. when reading a webpage, sometimes the spinning cheerio keeps flashing on and off. it's distracting. it may be the rss feeds refreshing, but this does not happen in ie9.

    I know you get a lot of flak, but I wanted to express my thanks on behalf of web developers everywhere.  The list of new standards support in IE 10 likely represents the largest advance in web standards, in any release of a web browser, ever.  Kudos to your team!

    Hi Thanks for another great post. I absolutely love the new ie 10 preview. I have a totally unrelated questions. Last few days, I started noticing my windows phone ie browser display twitter content very strange and different from before. Can someone from mobile ie team check to see what happens? I am very frustrated. Thanks,

    I really like seeing the new feature list in IE 10, but the IE team needs to break their release cycle from the OS release cycle.  Many of these features should have been out in the market six months ago.  There should be an IE 9.1 release.  The browser market is very fast these days and the Microsoft release cycle ignores that fact.

    Xero's #2 is a serious issue that I'm also experiencing. Unexpected shutdowns cause IE9 to completely forget a lot of session cookies and logons. @rkupinski: I believe it was already stated that IE10 has an internal autoupdate (separate from Windows Update).

    will we get ogg audio built-in? Will 64bit IE have the new javascript rendering engine?

    Hey audience.. Take a look at the MSIETeam's copy-paste reply here... connect.microsoft.com/.../one-missing-and-another-poorly-implemented-shortcut If you think about it.. it would hardly take one minute to write two lines of event-handler code for both the shortcuts! But they Won't fix anthing!!!! Do you honestly think that I or anybody should continue to send them feedback?

    It would nice if you could overhaul the Internet Options screen and generally everything in tools.  IE10 looks great, until you look at the options. Additionally background tabs have too much influence over the performance of the foreground tab.

    @Xero Obviously it's a known issue for years but apparently none of the people working at Microsoft have ever had their computer unexpectedly shut down/restart so they'll never be able to reproduce it. social.technet.microsoft.com/.../0aaa80c3-87d3-4ea8-bd3a-c4f1e5b5ce39 answers.microsoft.com/.../6fbe0594-e14f-43c3-a393-c9f52a22b296 superuser.com/.../why-do-i-lose-my-cookies-when-internet-explorer-is-not-shut-down-correctly connect.microsoft.com/.../lost-all-cookies-logged-off-from-all-sites-and-frequently-used-sites-about-tabs-list-without-doing-anything connect.microsoft.com/.../cookies-lost-upon-crash-or-unexpected-exit connect.microsoft.com/.../ie9-loses-cookies (Closed as by design.... really?) etc. Don't get your hopes up.

    I was told by someone from MSFT that this cookie loss issue is probably due to how IE uses "memory managed" approach or something. Not sure if they fixed it in ie10 yet.

    The link to IE10 PP4 is wrong, it should be blogs.msdn.com/.../html5-for-applications-the-fourth-ie10-platform-preview.aspx "Some [features] are new [since IE10 PP4] in the Consumer Preview" Which features are new since IE10 PP4?

    I just want to echo @Xero's post: ANY time there is a less than perfectly clean shutdown of IE9 and IE10, it loses all sorts of info... saved passwords, the "new tab" page of most recent sites, etc, etc.  This is really unacceptable, and happens way too frequently.

    @etacarinae1 All of those things are really important.  Maybe if EVERYONE constantly submitted them over and over, Microsoft and the IETeam (and its management) might get a clue about how important they are, and they'd stop closing them as "working as designed" or "will not fix".  It's amazing to me that they're so closed-minded about things that are so vital to a good experience of using IE.  Items 2 and 4 ESPECIALLY. Please IEBlog/IETeam, please give these things a significantly higher priority, and stop ignoring your users!

    @Ted Johnson [MSFT], I reported the same issue to you as Xero and others are reporting, via email and you sent me the following reply: [Quotes] The larger question is, why does the system shut down unexpectedly? That seems to be the problem to solve. —Ted Johnson for IEBlog [/Quotes] Please read the comments, they have better way of reproducing the issue. You can search on the Internet that how many people are suffering with this unacceptable bug! Some people must have switched their browser as well for the very reason.. Now, the more bigger question is; do you guys really care? Or you want me to log "another" bug report on connect which them boys will close "By Design"? None of the real Microsoft developer visits Connect.microsoft.com and windowslivehelp.com... i have seen and submitted many many important scenarios to reproduce bugs but they consider it as a default behavior.. looks like MS (or atleast IETeam and LiveTeam) needs to revise their development lifecycle (frequently incorporating bugs) in order to catch up with the competitors! I know I know my comment will be a history and MS don't even give a sigh.. but u no filthy old habbit to send feedbacks! An example of the situation at Windows Live "HELP" .. windowslivehelp.com/thread.aspx ^^if this would be sent to a Live development team member, they would have fixed it by now! but MS hav outsourced their support to some metal-heads-bots, who copy/paste the same answer no matter what you tell them..... OP mentioned no MVPs for Windows Live! and none for IE... just because both are freee products !! tut-tut MSIE and MSLive teams.. you are losing just because you are missing the MOST cardinal rule.. "user's feedback"!

    For me, IE never really saves my history even though its turned on.  Plus it loses my recently visited websites (when you start typing in the address bar and it gives suggestions) pretty regularly which is really annoying.  Right now my history has 10 websites, only one of which I've viewed today.

    Can MS help audio/video formats not in the W3C standard get into the standard?  This would help popular but non-standard formats make it into IE.

    Because of this gap in the market and no cost to me, I have become a Chrome vLatest user now, and more recently started exploring the idea of their apps. Wouldn't have given it a second thought normally but the more I read this blog the more I feel I am missing out on the new..

    [Feature requests]

  • Download Hub: Introduce the ability to add files URLs manually in IE10's download manager -- preferably *.torrent support too!(connect.microsoft.com/.../create-download-in-ie-download-manager)
  • Please make the quick-tabs (CTRL+Q) shortcut enable by default and display some extra information like memory/CPU-cycle consumption per-tab! [Shortcut request] "While holding Ctrl, if we click back or forward button of Windows Explorer or Internet Explorer, the corresponding page should be opened in a new tab (in case of IE) and new window (in WinExplorer's case). This shortcut is present in EVERY non-IE browsers so at least provide this missing shortcut in IE10." [Incomplete implementation of a shortcut] "While holding the Ctrl button if you press 0 (zero) on qwerty keyboard, the zoomed page is reverted to normal. But if the 0 is pressed on numpad, the shortcut doesn't work. Since Ctrl + numpad-0-key is not reserved for any action, please override this shortcut as EVERY non-IE browser does." Pleaseeee consider thes requests for IE10 RTW/RTM release.. I always use Ctrl+num0 and Ctrl+browser-back-button(or Ctrl+browser-forward-button) in FF.. would be very much obliged if you guys make them available!

    Hello! Has Microsoft confirmed that it is going to provide Internet Explorer 10 for Windows 7? I tried searching in Google for a post in this blog, but couldn't find any. If they DID say it somewhere, can someone please provide a link to the post where either in the article or comments, MSFT has said it will support Win7 for IE10?

    @hAl - Thank you :) I second @Real McCoy.. Ctrl + NumPad 0 is a must. I hardly use the regular number keys anymore. I have to consciously sharpshoot the regular zero in IE :( Oh by the way, I am not able to file anything in Connect because it keeps telling me that the IE programs are closed for feedback and bugs (?!)

    The ongoing development of IE10 is looking fantastic! Is there any chance that there would be support for ECMAScript6 (ES.next/Harmony) features like WeakMaps, Proxies, Maps, Sets, etc. before the final release? ES6 support is emerging on both Firefox: developer.mozilla.org/.../ECMAScript_6_support_in_Mozilla and Chrome: blog.chromium.org/.../future-of-javascript-take-peek-today.html It would be awesome to be able to use IE10 with these features too! Thanks.
